About 0UWM00Z

0UWM00Z is the ICD-10-PCS code for a revision procedure on the vulva using an open approach with drainage device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to other incision of vulva and perineum, the ICD-9-CM procedure title it maps to (71.09).

For a different body part, codes include 0UW300Z (ovary), 0UW800Z (fallopian tube), 0UWD00Z (uterus and cervix) and 0UWH00Z (vagina and cul-de-sac).

The same procedure with a different approach is coded 0UWMX0Z (external).

With a different device, use 0UWM07Z (autologous tissue substitute), 0UWM0JZ (synthetic substitute) and 0UWM0KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC), DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), DRG 746 (Vagina, Cervix and Vulva Procedures with CC/MCC) and DRG 747 (Vagina, Cervix and Vulva Procedures without CC/MCC), under the surgical categories “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Vagina, Cervix and Vulva Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
